The audio amplifier amplifies the low gain signal to a high amplitude signal which can drive a speaker. To power the circuit, we have a +12V battery pack with BMS. The 12V battery pack is connected to ...

The complete circuit diagram for Arduino Based Decorative Christmas Tree is given above. It is pretty simple as we only need to connect a PIR sensor, JQ6500 voice module, and Neo-Pixel LED Strip. The ...

The OpenBMS system is powered by an Arduino Nano controller and is programmed using Arduino. The system constantly monitors battery parameters and instantly cuts off the input or output from the ...

Before assembling the circuit, do not forget to upload Motion_Detection.ino on the Arduino Nano board. After assembling the circuit on the PCB, connect the PIR sensor across CON1 and 12V across CON2.
